And it said........Time to get new seat bushes you fat git !!!!! 
Just ordered a set from Aceman through the forum, Might as well replace them in both seats even though only the drivers seat was rocking. ( as I was reminded more than once !!)
Fortunately there are detailed instructions of the procedure on the forum so don’t see any real problems in swapping them over.
